The HB TCXX is the latest evolution in
touring car technology, from the World Championship-winning HB
racing team. Champions never tire and never slow down, and the TCXX
has been in development since the release of the last HB touring
car. Now, with the will and spirit of World Champions behind it, we
present to you the HB TCXX.

Perfect Balance - Optimized for the Latest LiPo
Gear

Taking the ultimate balance concept of the
TCX, the TCXX features a battery position that is set inboard as
much as possible, with the motor mount further to the left to help
compensate for the light weight of today’s servos, receiver
and speed controllers. The TCXX can also fit the TCX motor mount if
you prefer to have the motor further inward.

Total Control

As well as a huge number of option pieces from the TCX and TC-FD
that allow you to precisely control such parameters as roll center,
front and rear arm toe, camber, caster and more, the TCXX allows
you to fine-tune the grip front and rear with sway bars front and
rear, a front spool and an all-new gear differential that lets you
forget about the complex and repetitive tuning necessary with
traditional ball differentials.

All-New Chassis

The TCXX 2.5mm chassis is extra-narrow to
prevent any rubbing in tight corners. The 2.5mm woven graphite is
of the highest possible quality. New carbon battery holders are
included to hold the battery pack securely in place.

The inner pivot blocks are a new split
design to allow the chassis to flex much more than is possible with
single-piece designs, giving you more grip and confidence in the
corners and while under power. You’ll experience a new level
of control as your hold the racing line while you’re
door-to-door with your fellow racers!

The one-piece top deck ensures completely equal flex over the
entire car. This gives you a more balanced drive and equal
handling, with a much lower chance of tweaking the car after a
crash. The fully symmetrical top deck features 4 mounting holes at
the front and 8 holes at the rear bulkheads, allowing you to tune
the flex level for different traction levels. You also have a
central hole to allow the mounting of TC-style single bellcrank
steering – the option is yours! The 2.5mm thick woven
graphite is of the same quality as the main chassis, meaning it's
the absolute best we could find. Finally, the top deck also holds a
belt tensioner, which keeps the front belt in place during hard
braking.

Compact Bulkheads

The bulkheads carry on the TCX fully symmetrical design, and are
the same front and rear, and also left to right. Featuring an
extra-compact design, they allow you to run extra-long top links
for increased suspension action, and the belts are also able to run
as close to the centerline of the car as possible. Our eccentric
cam belt tensioner is used to tighten up the belts as they break
in.

Servo Mounting

The new aluminum servo mounts for the TCXX hold the servo in
place more securely across the chassis for extra confidence and
better driving feel. The TCXX is designed for a
‘shorty’ type servo but can fit standard-size servos if
you mount the receiver on top of the servo.

The TCXX uses many of the same
suspension parts that the TC kit uses, with reversible lower arms
for extra shock positions, droop screws, steel turnbuckles, plus
easily adjustable parameters such as wheelbase, track width,
anti-squat, toe-in and roll centre for complete adjustability. The
super-narrow bulkheads are taken advantage of with longer top
links, which make the car easier to drive faster through the turns
as the allow the suspension arms more movement.

Fine Pitch Shock Towers

The front and rear shock towers are made from the
highest-quality woven carbon fiber available. At 3.65mm thick, they
easily support all the load from the shocks and wheels! These are
extra tough, extra stiff units, with 7 front shock positions and 8
rear positions in a linked hole style, for extra-fine track
adjustments.

Upgraded TCX Shocks

The shocks fitted on the TCXX are an evolution of the units that
came on the TC and TCX - meaning they are even better than our
World Champion-winning shocks! The upper and lower ends of the
shock body feature extra fine-pitch threads for the shock caps, and
the bottom end uses a single o-ring design for minimal 'stiction' -
that initial grab that an old and tired o-ring can give the shock
shaft. An all-new aluminum spring retainer and spring adjuster are
used for extra ease of tuning and a sweet new look. Inside the
shock is a new PTFE 3-hole shock piston with 1.1mm holes, plus a
PTFE shock spacer for extra-smooth movement. The shocks perfectly
fit the full range of HB High Quality Matched Springs, #66961-#66965.

Twin-Crank Steering

New for the TCXX is a longer twin-crank steering design, which
makes the most of your control inputs and gives you more steering
throw as well as fantastic driving feel on the track. The aluminum
bellcrank arms float on metal-shielded ball bearings to maximize
efficiency and give extremely smooth response. A woven graphite
steering tower bar braces the steering posts for the best steering
feel you’ll find from any of today’s top-level touring
cars. The steering Ackerman angle is also easily adjustable with
shims under the rack ball studs. Our drivers say this steering
design gives them more corner speed over the older TC-style central
steering system, but if you prefer the TC steering, it is possible
to fit the centre steering system directly onto the TCXX.

Full Set of Sway Bars

Infinitely adjustable ball stud sway bar mounts are included to
let you instantly de-tweak the car so it's quickly ready to go for
your next race. In the TCXX kit you will get a full set of front
and rear sway bars to fine-tune the suspension at each end of the
car. The kit includes 1.2, 1.3 and 1.4mm sway bars for the full
range of HB options.

Centralized Low-Profile Motor
Mount

The new motor mount sits completely under the top deck, a
features two sets of mounting holes to let you choose how the motor
mounts into the car. The motor mount is further to the left than on
the TCX, to help compensate for the light weight of today’s
servos, receiver and speed controllers, however it can also fit the
TCX motor mount if you prefer to have the motor further inward,
allowing you to tune the balance of the car without having to
resort to lead weights.

Central Belt Layout

The drive belts front and rear have been arranged so the rear
belt is on the left side of the car, with the front belt on the
right side. This allows the servo and electronics gear such as
receiver, speedo and transponder to sit closer to the centerline of
the car, improving the balance immeasurably over older touring car
designs.

Quick-Change Layshaft and Pulleys

The TCXX uses one-piece pulleys fit on the layshaft with a
simple pin fastening, eliminating the grub screw of earlier
designs. The layshaft is narrower, owing to the more compact
drivetrain design, and also uses a simple one-piece spur gear
mount. With 20T center and 39T pulleys front and rear, the TCXX is
more efficient at getting the power to the tyres than older car
designs. The TCXX can also use the center gears from the TC-FD for
even more control in the gearing between the front and rear
wheels.

Extra-Lightweight Front Spool

Every racing electric touring car these days is fitted with a
front spool to eliminate diff action, greatly enhance braking and
increase traction. and the spool fitted in the TCXX is an
extra-strong lightweight 3-piece design. The central part of the
spool is machined from lightweight aluminium, then anodized bright
purple. The outdrives are machined from steel to be extra-strong
yet still light in weight.

All-New Rear Gear Differential

One of the developments in touring car racing where Team HB has
led the way is the use of a gear differential at the rear of the
car. This allows motors as powerful as 3.5 brushless motors to be
used time and time again, without having to worry about the diff
changing it settings – truly a ‘set and forget’
part of the car! Let the gear diff on the TCXX revolutionize your
maintenance routine!

Aluminium Universal Drive Shafts

The TCXX features new 44mm aluminum driveshafts at the front and
lightweight, thin, steel driveshafts at the rear for the optimum
combination of durability and light weight. Lightweight steel cup
axles are used for durability and strength, with a thick 2mm pin
for extra durability. The constant velocity design eliminates
wasted power, ensuring that when you want the power to hit the
ground, it will.

Even the smallest details are looked
after on the TCXX, and our World Team Drivers are always telling
our designers what they'd like to see on the newest kits. Below are
some of the minor, yet still important, details the TCXX offers kit
owners.

Battery Mounting System
Pro racers like to use fibre strapping tape to hold their batteries
in place, which is lightweight and perfect for their needs. The
TCXX kit comes with 'bumpers' to prevent LiPo batteries from moving
into the belt, as well as securing them in place front and
rear.

Hex Hardware
The TCXX uses a full set of black-coated hex-head
hardware throughout. Every screw, bolt and fixing uses
standard-size hex wrenches, ranging from 1.5mm to 2.5mm in
size.

Off-Road Style Antenna Holder
HB designers came up with an antenna holder that will keep your
antenna tube locked into position: a steel grub screw
secures the antenna in place from the top, gripping it
securely, no matter how rough a race you might find yourself
in.

A Proven Top Competitor!

IFMAR World Champion TQ and 2nd
Place!

At the world debut of the TCXX, Team HB
(featuring 2 drivers with 3 World Championships between them)
rocked the field with a dominating Top Qualifier position for
Atsushi Hara, who then went on to drive brilliantly in the 3 A
Final races. Hara missed out on snatching his third World
Championship by thousands of a second, but proved that the TCXX has
everthing that’s needed to be a winner straight out of the
box! Check out the full race report on RedRC! (photo
